Question

12.3:x-4.5 :x=15

 

Answer 1

\(12,3:x-4,5:x=15\)

\(\left(12,3-4,5\right):x=15\)

\(7,8:x=15\)

\(x=7,8:15\)

\(x=0,52\)

Answer 2

\(\text{12,3:x-4,5 :x=15 }\)

\(12,3.\frac{1}{x}-4,5.\frac{1}{x}=15\)

\(\frac{1}{x}.\left(12,3-4,5\right)=15\)

\(\frac{1}{x}.7,8=15\)

\(\frac{1}{x}=15:7,8=\frac{25}{13}\)

\(x=\frac{13}{25}\)
